This invention relates to new and useful improvements in dough moldingmachines and more particularly it pertains to machines for molding cockydough.

One object of the present invention is to improve the construction andmode of operation of dough molding machines of the afore-mentioned typeand to provide such machines with mechanism which `will effect a bettermolding opera- 1.; tion than prior machines.

A feature vof the invention resides in a new and novel mechanism 'andarrangement of parts whereby the thickness to which the dough isdeposited in a pan in which cookies are baked u may be determined at thewill of the operator.

A further feature of the invention resides in a new and novelconstruction and arrangement of parts whereby a plurality of batches ofdough,

each in itself sufficient to form a wafer-like body or cocky may bedeposited in a baking pan at a single operation.

A stili further feature of the invention resides in the provision oinovel means' for distributing the individual batches of dough in abaking pan.

Still a further feature of the invention resides in a novel constructionof hopper'from which the dough is discharged to the machine togetherwith a novel dough discharging mechanism Still a further feature of theinvention resides 3 lin a new and' novel construction whereby thedepositing of excess dough is obviated, the mechanism depositing onlysuch dough as ultimately forms individual batches from which the cookiesare baked. 4

Other features of the invention relate to certain novel and improvedconstructions, .arrangements and combinations of parts hereinafterdescribed and particularly pointed out in the claims, the advantages ofwhich will be readily under- 4U stood and appreciated by those skilledin the art.

A machine constructed in accordance with the present invention comprisesa bed i5 supported upon a suitable base iii which in turn may be securedto a 'bench table or other suitable support not shown by means of bolts,lag screws or the like Vi'. The bed portion comprises side plates i6 30which are spaced from each other and which are maintained in operativeposition by being secured to the base member 20.

Mounted between the side plates and arranged for vertical movementtherein, there is a framelike member 2| and depending from saidframelike member upon opposite sides thereof, there are rack bars 22.The rack bars 22 are connected on'their lower ends to a secondframe-like member 23 which comprises vertical portions 24 andlongitudinally extending members 25 connected by transversely extendingmembers 26 and 21.

It will thus be apparent that the upper frame 2l and the lower frame 23are rigidly secured together and move in unison by a mechanism to 45 benow described.

Mounted in bearing blocks 28 which are rigidly carried by the sideplates I8 there is a shaft 30 and this shaft 30 carries two worm gears3| which mesh with worm gears 32 carried by shafts 33 50 suitablysecured in the base 2U. The shaft 30 also carries twogears 34 which meshwithigears 35 carried by a. shaft 36 which in turn is operated by ahandle 31. Carried by the shaft 30 and meshing with the rack members 22,heretofore 55.

mentioned, there are two gears 38. The shaft 36 which is operated by thehandle 31 is likewise mounted in the bearing blocks 28, heretoforementioned.

From the foregoing it will be obvious that as the shaft 36 is rotated bymeans of the handle 31, the shaft 30 will be driven through the mediumof the'intermeshing gears 34 and 35 and through the medium of the gears38 which mesh with therack bars 22, both frames 2| and 23 will be eitherraised or lowered, depending upon the direction of rotation of the shaft36 by the handle 31. The pitch of the spiral gears 3| and 32 is suchthat regardless of the position to which the frames 2| and 23 are moved,they will be maintained in this position by the intermeshing of thespiral gears and thus hold the framel in its adjusted position. However,it is to be understood that the spiral gears are so constructed as topermit of movement of the frames by the mechanism above described underthe influence of the handle 31.

The upper frame 2|, heretofore mentioned, constitutes a pan support andis adapted to support a, baking pan 49 on the upper surface thereof.

The reference numeral 4| designates a diey plate which is provided witha plurality of openings 42 through which the dough is passed onto a pan40 carried by the upper frame 2|. The spaced relation of the pan 40 andthe die plate 4|. determines the thickness of a batch of dough deliveredby the openings 42 in the die plate, and means is provided to adjust orvary this spacing and consequently the thickness of the batches of doughdeposited in the bakingl pan in order that cookies of various thicknessmay be formed.

This means comprises substantially U-shaped stops 45, as illustrated inFigure 8. Each of these stops comprises two vertical legs 46 and 41connected by a. portion 48. The leg 41 has an elongated slot 49 therein,and as illustrated in Figure 6, this slot is adapted to receive a bolt59 which is threaded as at 5| into the side wall I8 of the machine. Itis to be understood that there are preferably four of these adjustablestops being arranged one at a point closely adjacent each corner of themachine. The leg 46 of each of these stops projects downwardly alongsideof the die plate 4| designated at 55 in Figure 6.

By this construction it will be apparent that as the upper frame 2| iselevated in the manner heretofore described, the baking pan 4l) will beelevated until it reaches the point .where it engages the lower ends ofthe legs 46 of the adjustable stops 45, which engagement will arrestfurther vertical movement of the upper frame 2|. Therefore, by adjustingthese stops 45'the spaced relation of the pan 40 and the die plate 4|may be varied consequently varying the thickness of the batches of doughdelivered through the open- Y ings 42 of the die plate and therebydetermine the thickness of the flnished product.

Means is provided to spread the dough over the die plate in order thatit mayv pass through the openings 42 therein, and this means comprises ahopper 66. The hopper .69 has a cover 6| which is preferably hinged, asillustrated in Figure 1 and two operating handles 62. This hopper ismounted for sliding movement longitudinally of the machine to dischargecooky dough upon the die plate during such movement in order that thedoughmay pass through the openings 42 of the die plate. Y

To provide for sliding movement of the hopper 60 trackways 65 areprovided. These trackways,

`a spring 96.

as best illustrated in Figure 6, constitute channel members 66 havingtheir open side 61 positioned inwardly of the machine. These trackwaysare carried by suitable supports 68 spaced with respect to the upperedge of the side plates I8 by supporting posts 69. The hopper 60 issupported by carriages 18 as shown in Figure 5. These carriages consistof angular members having vertical portions 1| and horizontal portions12, the latter being received in the trackways 66. The carriages 1| areretained in position in the trackways by means of an angular member 13which is carried by the trackways and removably at- 4 tached thereto bybolts or the like 11.

The hopper comprises two members, an upper member in which the dough iscarried and alower member in which is mounted means for discharging vthedough from the hopper.

By reference to Figures 9 and 10, it will be noted that the lower membercomprises end walls 18 and side walls 19 suitably secured together. Theend walls are held in spaced relation by the side walls 19 and said endwalls have extensions 80 provided with perforations or openings 8|.Theseopenings 8| are adapted to receive spring bolts 82 carried y in ahousing 83 which in turn is mounted upon each of the carriages 10,heretofore mentioned. By moving theseI spring bolts 82 outwardly oftheir housing, the inner ends thereoi will be disengaged with respect tothe openings 8|, heretofore mentioned, and leave the entire hopper freelto be removed from the carriages 18.

As illustrated in Figure 9 there are two of these spring bolts at eachend of the hopper and they are connected by means of a single operatinghanf dle 98 in order that they may be operated in unison. By referenceto Figure 12 itwill be noted that these bolts are also connectedadjacent their inner ends by means of a bar 9| which is secured to thebolts by set screws or the like 92. The bolts are slidably mounted inthe housing 93, the upper wall of which is provided with an opening 94.Carried by the bar 9| there is a spring pressed locking pin 95 which,when the bars are pulled outwardly of the housing 93 by the handle 90,engages in the opening 94 to hold the bolts 82 in their retractedposition against the tension of When the bolts are retracted the hopperis free to be removed, as heretofore described. When itis desired toattach the hopper to the carriages the hopper is positioned and thelocking pin 95 disengaged with respect to the opening 94 at each end ofVthe hopper, whereupon the springs 96 will tend to force theirrespective bolts into engagement with the openings 8| in the extensions80, heretofore mentioned. The locking pin 95 is released with respect tothe opening 94 by means of a trigger-like member 98, the free end ofwhich extends to `a point adjacent the handle in order that it may bedepressed by means of the fingers of the hand grasping the handle 90. Y

From the foregoing it will be apparent that a hopper may be removed fromor attached to the .carriages at will.

The upper part of the hopper designated 69 is removable with respect tothe lower part in order that the hopper and its several parts may bedisassembled for the purpose of cleaning. To accomplish this the sidewalls 19 of the lower por- 'tion of the hopper .are provided in theirlower edges with slots |00 which receive bolts 18| car-y ried by theside walls of the upper portion 60 of the hopper, which bolts, whentightened, will provide means for securing the two sections of thehopper together, it being understood that the side walls of the upperportion of the hopper are received within the side walls 19 of the lowerportion of the hopper.

The lower portion of the hopper has a disfrom the hopper into thetubular member 01 and to discharge the dough through the opening |08thereof. This agitator is adapted for rotation and to effect saidrotation vit is mounted upon a shaft llo, each end of which carries agear H2. These gears il 2 are adapted to mesh with rack bars l i3, asillustrated in Figure 5, in such a manner` that as the hopper is movedlongitudinally of the bed of the machine in either direction, theagitator Hill will be rotated to take the dough from the hopper anddischarge itthrough the discharge opening itt of the tubular member l'l.It is to be understood that the hopper is moved longitudinally of themachine by hand, the operator grasping either of the handles t2 for thispurpose.

The tubular member, the agitator and the shaft llt are retained in thelower portion of the hopn per by means of bearing disks l l5 carried bythe shaft lill and from which disks project angularly disposed threadedbolts llt adapted to be received in slots ii'l in the side walls 'le ofthe lower portion of the hopper.

l'rom the foregoing it will be apparent that the present inventionprovides for the adjustment of a baking pan with respect to the dieplate of a dough depositing mechanism in order that the thickness of thebatches of dough deposited may be varied at will and that means is alsoprovided whereby hoppers containing various types of dough may bereadily removed and placed upon the machine at will.

This machine operates in the following manner.

The dough being deposited in the hopper, and the adjustment of themembers l5 made, the crank 3l is grasped and the pan supporting membermoved vertically as described. In this vertical movement the pan willengage the lower ends of the legs it of the stops t5, thus limiting thevertical movement cf the pan. The pan will be held in this position byreason of the inner engagement of the spiral gears 3i and 32 and withthe pan is this position the hopper is moved from. one end of themachine to the other depositing the dough upon the die plate throughwhich it passes to the pan, depositing a full pan of coolqr batches.After this operation has been completed the pan is removed and theoperation repeated.

By this construction a single pan may be placed upon the pan support ora plurality of nested pans may be placed thereon and the pans removedfrom the pile as the dough is deposited thereon.

While the invention has been illustrated in its preferred form it is tobe understood thaty it is not to be limited to the specic constructionsand arrangements herein shown but may be practiced in other formswithout departing from the spirit and scope thereof.
